Great service




Overall it was a great experience. Set up appointment day before and got all the work done the following day. We had a billiard light installed and other home improvement electrical work done. Very professional and efficient and pleasent to deal with!

Great Service




We originally called Black Diamond about a water leak coming from our Bryant 560. David Fajardo was sent to handle for BD. David did a great job in explaining where and why the unit failed. His professionalism was refreshing ( and he is a Dodger fan. Just like us). Thanks again!

Jesus was polite and very helpful




I would be glad to have Jesus respond to any calls I have to Black Diamond and he is the main reason for my continued patronage of your company.

Love Black Diamond.




We have used Black Diamond for multiple projects for 10+ years. Always top notch service. Today was no exception. We had an electrical breaker malfunction and Black Diamond was here within an hour to repair

Great Service





perfect job done




Every person connected with our furnace replacement was great. The guys came to our home when they said they would. Left us with a great working furnace and cleaned up to the point you never knew they had been there.


Great Customer Service Experience with Jesus Galvan




Jesus was professional, friendly and got the job done quickly. He kept me informed during the duration of the repairs what had happened and what he had to do to fix the problem. A+ experience!


Jesus was awesome!





Hot Water tank Replacement




our experience was very positive. The Technician was prompt and courteous. He detailed the work to be done and completed the job efficiently. Very neat worker, and did not leave any mess in the basement. He was very helpful in explaining features of the new heater and giving me maintenance tips.


Professional, Efficient, Helpful




We had Black Diamond out to add Humidifiers to our furnaces. The two fellas that came out did a great job! We are totally happy with the work they did and their positive attitude. They not only did the job we asked them for but they took the time to help me better understand some details about our furnace (we recently purchased the house). And all for $300 less then a competitor's quote.


Great service

Jorge was great. He did a great job and cleaned up. He waited and tested everything
